IMPROVEMENT IN THE CNSTRUCTIN OI' PICK-AXES.

TheScheduJe referred to in these Letters Patent anddmakng part of thesame.

To all whom 'it concern Be it known that 1,M0RGAN GALE, of San An'-tonio, Lower California, Mexico, havenvented a new and usefulImprovement in Pick-Axes; and I do hereby declare that the following isa full, clear, and exact' description thereof', which will enable othersskilled in the art to make and use the same, reference being had to theaccompanying drawings, forming 'part of this speoication. e

yEigure l is a side View of my improved pick-axe, partly in section,through the'line x x, fig. 2*. Figure 2l isa detailseotioual View of thesame, taken through the line y y, iig. 1.

Similar letters of reference indicate corresponding parts. y

My invention has .for its objectyto improve the construction ofpick-axes, so as-to make them stronger, more durable, and less likely tobecome loose upon the handle than when constructed in the ordinarymanner;

and it consists-in the detachable socket, in combiua.

tion with the handle and head of the pick-axe, as hereinafter more fullydescribed;

A is the handle, and B is the head ofthe pick. The eye of the head/Bismade tapering, so as to be larger upon the outer than upon the innersideof said head, so that the end o'f the handle A, When'wedged intoitsf'place, may be morexrrnly held than Ait would be if said-eye weremade straight.

C is the socket, which tapers slightly in the other direction from theeye of the head B, so as to resist any tendency of the pick-head'to slipup upon the handleA.

The base, ol, of thesocket O, is extended along and fits upon the upperside of the pick-head B; to whichv its ends are secured by screwspassing through the ends of the said base, c, 'and screwing -into thesaid pickhead, as shown in fig. 1.

c2 are side-danges, .or braces, formed solid upon the socketU, in theangle between the body of the said socket and the base, o, so as tostrengthen and brace the said socket.

By this construction,the connection between the han'- dle and head ofthe'pick-axe, will be greatly strengthcned, and the 1 liability of thehead B to become loose upon the handle A will be greatly'lessened, thusincreasing the durability and eiciency of the tool.

I claim as new, and desire` to secure by Letters `Patent- The detachablesocket C, constructed with a base, c, with or without the side orbra-oe-iianges c2, in combination with the pick-head B, substantially asherein shown and described, and for the purpose set forth.

MORGAN GALE.
